IMPROVEMENT IN ELEVATORS FOR HODS, 84c.

Specification forming part of Letters Patent No. 110,195, dated June 24,1873; application filed February 18, 1873.

To all whom it may concern:

Be it known that I, EDWIN HARLOW, of the city, county, and State of NewYork, have invented an Improvement in Elevators for Hods, &c., of whichthe following is a specifi'cation:

This invention relates to an elevator which is constructed so that itcan be used for carrying up hods containing mortar or bricks, or it canbe used for elevating lintels, copings, or other materials not usuallycarried up in hods. Said invention also relates to a swinging platform,which is made so as to insure the safety of the workmen in removing orplacing the hods upon the elevator.

The elevator is made as a frame composed of two vertical posts connectedat the bottom to a platform and at the top to a cross-bar or rail, uponwhich are V-shaped racks or supports for the hods. Theseracks are in tworows, and intermediate to each other, so that the hods will not projectas far beyond the elevator as if the top rail was made wide enough toreceive the hods in two rows on line with each other.

The shanks or handles of the hods rest at their lower ends againstremovable bars, and

the hods are kept fromslipping from their supports by a pin on thebottom of each hod When the bars are removed from the elevatortheplatform can be used to receive materials which cannot be placed inthe hods, such as sills, lintels, &c.

The platform upon which the workmen stand in placing on or removinghods, stone, &c., from the elevator is made with swinging fiaps ordoors, which are kept raised by weights, and allow of the free passageof theelevator; but when depressed by the feet of the laborers, theynearly close the space between the stationary platform and the platformof the elevator, and prevent all danger of the laborers falling throughsaid opening, and at the same time free access is given to the elevator.

In the drawing, Figure 1 is a front view of said elevator, and Fig. 2 isa vertical section of the same at the line as w.

a represents the platform of the elevator,

' made with a suitable frame connect-ed to the vertical posts 0 0, whichare united at their upper ends by the cross-beam b. e e arefriction-rollers within mortises in the posts 0 0, and these rollers runagainst the inner faces of the guide-ways or bars ff, which extend fromfloor to floor of the building, and the elevator is guided by the pins 9g, which project from the posts 0 c and pass at both sides of the ways ff. Said guide-pins are preferably rounded at the sides next to thesurface of the guide-bars f,- so as to move freely. h h are the racks orsupports for the hods upon the cross-beam b, and these racks are in tworows, and the racks of one row are opposite to the spaces between theracks of the other row. Each rack is made with a V-shaped opening toreceive the hod, and the hods for one row are placed in the racks fromone side of the elevator, and in the other row from the other side ofthe elevator, and said hods com ing intermediate to each other, theyoccupy less space in width than if they were in line with each other;hence the opening between the beams through which the elevator passescan be made correspondingly small. The handles or shanks of the hodsrest at their lower ends against the removable bars I, which aresupported in sockets or loops m, upon the posts 0 0, and these bars keepthe hods properly in position; and to prevent risk of the hods slippingfrom their supports, each hod may be provided with a short pin, whichprojects from its bottom edge and sits behind the support h, as seeninFig. 2. The bars I 1 may be kept in place by pins 1 passing through theloops m and entering said bars, and when these bars are removed theplatform a can be used for receiving materials which cannot be carriedin hods, such as lintels, sills, &c. The stationary platform 0 isboltedto sill-pieces g, which are secured to the beams of the floorsupon which the materials are to be delivered, and upon these sills q arethe uprights r and cross-beam t. In the latter are mortises for theguide-ways f f, and s by a laborer placing his foot against it; and whenthese flaps are not pressed down, the

weights raise them, and the elevator and its load can freely pass; butwhen depressed as aforesaid, they afford a firm standing-place for thelaborers as they remove the hods from or place them upon the GlBVEttOl.

This platform and frame are to be removed from floor to floor as thebuilding progresses. The hoisting rope or chain 6 maybe connected to therod l and led over the pulley w, and thence to the hoisting apparatus;but this forms no part of my invention.

I claim as my invention- 1. The removable bars I, in combination withthe platform a and racks h for the hods, substantially as set forth.
